Application filed December 30, 19%. Serial No. lfi.

This invention. relateei'o improvei'nents in warp beanie for looms and it ie the general object oi the invention to provide improved ine-ane :tor etpii'ilizing the pressure exerted b v the iaieveral Strands into which aI warp ie divided when being tied to a loom beam eo that all. the threade` may be under the same tension i liilarpfi'hreade are usually attached to ay warp beam by beingl grouped together and tied in one way or another to eome part of the beani. llt ie lionnd a matter oil, practical. diflicultv to tie all olf `the groupe ol etrande under the name teneion and I have devi d f means 'whereby the diiieringr tensione oil.l the eeverai `tri-cupe may be equalized by a lier ible cord or cable held at its ende and hav ing; tied thereto at a plurality oi points 3intermediate ite ende oi the several `groupe or strands. @ne iform of beam for accomifliehing; thin reeult 'ie eet 'forth in my eol'iendinj.;` application Serial No. ifi-2,77. `wherein are Shown a number oi' hooke pivotally mounted. on the interior oi the beam and arranged to project through holes in the metallic shell or barrel of the beam. It is an important obj- :t oiv my present invention to iinijnfove upon the details of construction of the hooks and their support and aleo to provide eenvenient means ii'or securing the 'flexible cable to the beam so that the same may be tightened or slaclrened or renewed.

It is a :further object of the invention to provide means for attaching the flexible cord to a part of the beam accessible trom the exterior thereof and so located ae not to exert any appreciable lateral pressure on the froides 'for the cord.

Fig. S ie Fig. 9 a front elevation `oi one of the hook ineinbere Rei'ei'riirg to the d rawin eje, the wa rp beam comi'irieee a hollow metallic barrel. l() having' :'idjuetable talee heads 'll which may bd clamped to the barrel in proper longitudinal position by ineansoii bolts; l2. yThe barrel may have a` series oi.z aligned holes 13 for a, pnriioee to be set ilorth. The present inven tion :ie not concerned. with the false heads and any improved type may be employed.

Ae Iehown in Fine. 4i, 5 and G the barrel l0 has an end thereof provided with a pluralitv olf grooves 2O and if desired may beturncil internally as at 21 to receive a hab 2Q of' a friction drinn 2?). Bolts 2li secure the hub and barrel. together ae ehmvn in Fien il?, said drinn being jin-ovided With eloi'e 25 which may be aligned with the slots; for the reception oi." Said bolts. The web 2G oi" the drum 23 may be provided with spaced opcnan enlargementoi a portion of `ings 27 to facilitate the assembly oi' the device and afford access to the boltsy 24.-. iis shown in Fig. 4i; the end olif the barrel l() may be eet accurately against the web 2G oiif the beam or any other portion thereof.

That portion o'i': the beam which provider; 'for a cin'npeneation in the uneven teneione oill the various ntrande ot' warp eompriece a bar 30, which may be of Wood if desired, secured to the interior .ot the hollow barrel 1 0 an shown more ijiartienlarljv in Fig. S, by menne oi Wood Screw di. The bar is: formed with a groove 32 and nia),r have. one end ohaini'ered oil an at 3?. A. pluralit7 of metallic stri ie i/l. as Shown .in Fine. Il and i 8, are secured to one of the eidos olfA the :atri p an at 35 by means ot eerevvs 3G. Each `of said strips shown in Fig. 3 has a body portion 37 extending along a portion of the bar 30 and has formed :integral therewith a, plurality oit eye 'formingJ arme 38 which are bent as shown in Fig. 8 to form a substantially closed eye- 39. Said arms extends across the groove 32 and define with the same a series of pockets P into which extend the ends of hook members 4l. Each hook member, as shown in Fig. 2, has a bent end 42 to which may be secured one or another of the war'p strands IV, and which may project upwaidly through the holes 13 in the barrel. At-a point intermediate the pivotal ends 40 and the bent end 42 I form each hook with an eye 43 whichv lies between adjacent arms 38.

A fiexible coid or cable 50, which in this instance maybe made of metallic strands, extends through the eyes 39 and 43 vand may be secured to the beam in the manner set forth in Fig. 4. rAs shownv therein the friction drum 23 is recessed as at 5l to receive the head ofy a screw or bolt 52. rIhe end of the cable V50 is looped around the screw 52 and held tightly in place thereby as shown in Figs. 4, 5 and 7, the cable passing through one of the innei openings 27 asV shown in Fig. 5. By means of this construction the tension on the cable 50 may be varied and the same may also be renewed. It is desirable, though not necessary, to have the cable v extend substantially parallel to the axis of .the beam from the last eye 39 to that part of the drum in which it is secured, as set forth in Fig. 4, this construction relieving the bar 30 and eyes of any lateral strains.

The groups of warp threads are fastened to each hook one at a time, the hooks being projected throughthe holes 13. The cable yields so as to equalize the different tensions .of the several groups and all the threads are found kto be under substantially the same strain.

From the foregoing it will be seen that I have provided a warp beam having metallic strips secured to the interior thereof and defining with a groove formed in the carrier bar pockets to receive the ends of the hooks. -It will further be seen that the cable 50 is secured to the beam near the outer pait of the drum 23 so as to be readily accessible and that the point of attachment is substantially in alignment with the fixed eyes through which said cable passes,

Having thus described my invention it will be apparent that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention, and I do not `wish to be limited to the details herein disclosed, but what I claim is:

1. In a warp beam for looms having a hollow cylindrical barrel, a carrier bar secured to the interior of the barrel and having a longitudinal groove therein, guide members secured to the barand having portions thereof extending across the groove to define pockets, hook members having portions projecting into the pockets to be pivoted therein, and a flexible member guided by said members and having operative engagement with the hook members, said flexible member being normally slack.

2.

4. In a loom warp beam having a hollow barrel, a carrier member extending along the interior of the barrel, a guide member formed with guide eyes, hook elements having portions extending between the members for pivotal support, and a fiexible member supported and guided by said guide member and'operatively related to the hook elements. v 5. In a loom warp beam having a hollow barrel, a head fixed to one end of the barrel, a guide member on the interior of the barrel having guide eyes, hook elements on the interior of the barrel pivotally mounted with respect thereto, and a flexible member operatively related to the hook elements and extending through the guide eyes and secured to the head at a. point substantially in alignment with the guide eyes.

8. In a, loom Warp heein having o hollow barrel, a heed fixed to one end of the barrel, :t guide member on the interior of the barrel having guide eyes, hook elements on the interior of the borrel pivotelly mounted with respect thereto, and a flexihle `men'iloer operatively related to the hook elements and extending through the guide eyes and detztelnlhly seeured to the heed in position to he disconnected While the heed is in its normal poelton with respeet to the barrel,

9. In e loom Warp beam having ar hollow barrel, a head fixed to one end ol' the barrel, :i guide member on the interior ol? the barrel hatving` guide eyes, hook elements on the interior of the barrel pivotelly mounted with respect thereto, and e flexible member operatively related to the hook elements and extending through the guide eyes end detaehably secured to the exterior oil the heed et a point substantially in alignment with the guide eyes.
